Toshiba OCZ VX500 512GB SSD Review

ATTO & CrystalDiskMark

ATTO v3.05

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB.

ATTO – VX500 512GB:

Benchmark Results: ATTO showed the Toshiba OCZ VX500 512GB SSD maxing out at 553 MB/s read and 521MB/s write in the standard overlapped I/O benchmark. Crucial rates this particular model at up to 550 MB/s read and 515 MB/s write, so that appears to be pretty accurate.

CrystalDiskMark 5.1.2 x64

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.

CystalDiskmark – VX500 512GB:

Benchmark Results: The VX500 512GB drive reached 540 MB/s read and 509 MB/s write in the standard sequential write test. The Random 4K performance on the VX500 512GB drive was 24 MB/s read and 127 MB/s write. When we ran the test again set to 0Fill mode and all the scores remained basically the same.

Let’s look at some other benchmarks!
